This 10-part series explores the science behind football. Running about four to five minutes in length, each video features an NSF-supported scientist explaining a selected scientific principle, while athletes from the National Football League (NFL) describe how these principles apply to their positions on the gridiron. A lesson from Lessonopoly accompanies each segment. Mathematical videos cover topics such as vectors, with quarterback Joey Harrington; projectile motion and parabolas, with punter Craig Hentrich; kinematics with running backs Deuce McAllister, Marshall Faulk, and Lousaka Polite; the geometric shapes of spheres, ellipses and prolate spheroids, with wide receiver Antonio Freeman; Newton's Second Law of Motion, with kicker Morten Andersen; torque, with tackle Orlando Pace; and the Pythagorean Theorem, with linebacker Hardy Nickerson. Highlight clips from professional games intersperse every video, along with slow-motion, high-speed camerawork that allows for frame-by-frame illustration.
